Uninstalling a ClickOnce application silently

We have an production application that is deployed using Visual Studio's built-in ClickOnce deployment tool. I am writing a batch file to uninstall the application:

rundll32.exe dfshim.dll,ShArpMaintain AppName.application, Culture=neutral,
PublicKeyToken=XXXXXX, processorArchite开发者_开发问答cture=x86

The batch file works and the application's uninstall is called. However, I'm looking to do this silently. I have tried /Q /q /S /s /Silent but with no joy.

How can I do this?

---

I do not want to hide the batch file window. Only the ClickOnce window.

---

Since there seemed to be no good solution for this, I implemented a new ClickOnce uninstaller. It can be called via command-line, from .NET, or integrated into a WiX setup project as custom action.

https://github.com/6wunderkinder/Wunder.ClickOnceUninstaller

We used this for our Wunderlist 2.1 release, where we switched from ClickOnce to a Windows Installer package. It's integrated into the installation process and completely transparent to the user.

---

I can confirm that WMIC doesn't work for ClickOnce applications. They are just not listed in there...

I thought of putting this here as I've been working on finding how to resolve this for a long time now and couldn't find a complete solution.

I'm rather new in this whole programming thing but I think this could give ideas of how to proceed.

It basically verifies if the application is currently running, and if so, it kills it. Then it checks the registry to find the uninstall string, put it in a batch file and wait for the process to end. Then it does Sendkeys to automatically agree to uninstall. That's it.

You could try to use Hidden Start.

---

You can not suppress the uninstall dialog for a ClickOnce application. You can write a small .NET application to uninstall the ClickOnce application and programmatically hit the button on the dialog, so no action is required by the user. That's about the best you can do.

Don't over complicate it & keep it simple - this works on both Windows XP & 7:

Go to Add/Remove Programs and make note of the exact name of the program. Open Notepad and paste the text below:

wmic product where name="PROGRAM NAME" uninstall

but make sure to type the exact name of the program in between the quotation marks and chose Save As /All Files and name the file Uninstall.bat and then test it out to make sure it works.
